Why is my TV recognizing my console as a different one?

About an hour ago or so, my TV somehow was recognizing my PS3 as my PS4 and shows the HDMI channel as "PlayStation 4" when I literally had my PS3 connected to the TV this whole time. Is there a way to fix this? It showed as "PlayStation 3" for several months, basically from last year.

I've tried to unplug the HDMI ports, deleted HDMI channels, and turning off and on my PS3 for my TV to recognize it. Nothing worked so far...
