It looks normal to me for a 1980s tv, but it’s been a long time since I’ve seen one. I remember it being almost unwatchable during the day with the curtains open. I suspect that the bleed comes from the digital camera capturing the crt scan lines as they are refreshing, which would be too fast for a human to see.

Edit: like the other commenter said, it’s going to be the Moire effect. https://nyanpasu64.gitlab.io/blog/crt-photography/
