@udengoogle First i must say i didn't see your device is listed in the logo page, in first line 😅
So bootlogo is ready for your device like you saw yourself.
Second, Ubuntu Touch is a community project, so not only core devs can improve it, and bootlogos are trivial enough for not being a priority for them, and be done by other members of comunity.
Now if you want your fresh installed new logo be part of the ubports ubuntu touch image for your device, you can ask it on a ticket on ubports git.
