I’m pretty sure every player does this.

I can't say for sure, my eyes are older now and I don't sit that close to the TV anymore to notice these things.

It’s been a while since I looked at any schematics but the players I was looking at use a pretty low end system for on screen display. LD players aren’t computers. The thing what makes the LD video signal is a totally different system than what makes text. They are combined later. I think they just use a notch filter to drain the color and all text is %100 white. Same as any VCR or TV from the same period.

What matters is what actual LDs look like when playing.
