it says right on this wiki in the Rinnegan

While its progenitor was first seen in Kaguya Ōtsutsuki as the Rinne Sharingan, its true form first manifested in her son, the Sage of the Six Paths

Uh, all that means is that the Rinnegan itself didn't appear until Hagaromo was born, and that the Rinne Sharingan was a similar but ultimately different dojutsu that gave rise to it. A similar statement exists for Shikotsumyaku:

"Kaguya Ōtsutsuki manifested a similar, albeit more lethal, ability [known as All-Killing Ash Bones] to weaponise her bone structure from which Shikotsumyaku originates."

This statement indicates that All-Killing Ash Bones gave rise to Shikotsumyaku, and in the same way, the above statement indicates that the Rinne Sharingan gave rise to the Rinnegan. There's nothing there suggesting that the Rinnegan is the Rinne Sharingan's final form. And indeed, if this were the case, it would contradict the other two cases where the kekkei genkai/mōra weakened as it was passed down- All-Killing Ash Bones was diluted to become Shikotsumyaku, and the Rinnegan was diluted to become the Sharingan. Why would one of Kaguya's abilities weaken across generations and the other- the Byakugan- stay unchanged, but her Rinne Sharingan suddenly strengthen, before again weakening severely once it's passed down again? The descent is already complicated enough without throwing a curve like that in.

also we do not know if hamura had a better byakugan. for all we know his byakugan was perfect.

That would be a logical conclusion- but there's nothing in any canon material to elucidate that idea. Kaguya barely uses the Byakugan, but when she does, it seems to be identical to the standard one. (You could maybe make a very thin case that hers was better since it allowed her to circumvent an otherwise-impenetrable Perfect Susano'o, but it's never made clear if any sufficiently skilled Byakugan user could do so.) We don't even really see Hamura use it at all- we only see him in battle with it active, not what he actually did with it. So, for all intents and purposes, the Byakugan didn't change at all, or at best diminished ever so slightly, as it was passed down. So the question remains- why was the Byakugan unchanged, while the Rinne Sharingan went all over the place?

its logical if hagoromo inherited her Rinne Sharingan to its fullest in the form of the Rinnegan than hamura must have had the full form of the byakugan.

Unfortunately, however, that's a case of hasty extrapolation. If the Rinne Sharingan strengthened in becoming the Rinnegan, then yes, the Byakugan would've logically strengthened as it was passed down, too. But there's still no compelling evidence to suggest that the Rinnegan is a stronger Rinne Sharingan, and so there's no logical foundation for that assumption. And again, canonically, no such power increase for the Byakugan is indicated.

just look at this hagoromo had a Rinnegan but indra only had a sharingan so its safe to assume that Hamura's byakugan was evolved like hagoromos Rinnegan.

No, it's not. Again, you're making hasty assumptions. All we know right now is that Kaguya had the Rinne Sharingan, she passed at least part of it on to Hagaromo, and he thus got the Rinnegan. He then passed the Rinnegan on to Indra, and it weakened to the Sharingan. The Byakugan was never shown to have undergone any such changes- again, with the possible exception of piercing a Perfect Susano'o (which, again, was never confirmed to be beyond a regular Hyuga), Kaguya's Byakugan seems to be identical to the Hyuga's, and so there's no inherent reason to assume Hamura's was stronger. And even if we do assume so for the sake of argument, it would just once again illustrate how nonsensical these lineages are.

if we are going by what happened to indra"gaining a sharingan that went blind with over use" than it is safe to assume that Hamura's byakugan had no blind spot and all current byakugan have blind spot because they did not inherit all of hamura's power

You forget- the regular Sharingan does not cause blindness, and even the Mangekyo isn't guaranteed to do so (especially if one undergoes an eye transplant to get the EMS). It's also implied that the user loses their eyesight because the Mangekyo is too powerful for the retinas to handle over a long period- it's not that the dojutsu itself is weakening, it's that the user's eye is being physically damaged and shut down by the technique. Considering that the Byakugan has never demonstrated a Mangekyo-esque form (the Tenseigan notwithstanding), and that any visual complications caused by it are always temporary, I'm very dubious that the Byakugan's blind spot is the result of it "weakening".
