It has appeard a reddish discolouration in my macbook 14 but in only one section of the display

It comes and goes

Depending on the program I use it appears reddish in the darkest spots or shiny and like a blurry shadow

I haven’t been using it in the past week but two month ago I had a display replacement.

you have a hardware issue. I would take it back in.

check your Recent Service record—typically there is a 90 warranty on parts & labor:

you can plug in an external monitor and compare your results. External monitor comes direct from the GPU, bypassing your built in display.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment
