iPad now has yellow screen tint after being in storage for a year

I haven’t used my iPad in likely a year. Its power was depleted and it was stored face down in keyboard fold case. I powered it up fully and performed any updates it needed. I went through all the tips on getting rid of a yellow screen but none have worked. I actually think it may be the screen itself that is messed up, not connecting to any commands. If this is the case, is it fixable? Likely need to take to a Genius Bar to see if it is the screen or internal.
