OpenGD77

Errr, yes, 2 colors

1024 bytes, as I wrote

Nope. The bootimage is 1bit color depth. Any color format need more, hence drasticaly increase the data size (x-bits per pixel * width * height). For a 16 bits per pixel, with the GD77 screen size (128 * 64), it woud be 16384 bytes. Using 1 bit per pixel is 1024 bytes.
So, 1k vs 16k.

Hi,

I don't see the reason to use a lot of storage space (and it won't fit anyway) for something you see, maybe, once a day. It's just eye-candy.
Plus, now you can define background and foreground colours.

Cheers.

Again, it's a matter of carrier, audio has nothing to do here.
The main goal is to help blind Hams to know when something happens on the QRG.
So, if this annoys you, disable it, simple.

So, you have two choices: disabling the rx beeps, or edit the channel details and turn Ch Beep off.

I think you need to re-read the user manual about rx beeps, as it is related to carrier and/or talker, but not with squelch opening/closing.
