They look grey to me as well and as Wayne mentions, they don't look like the bolsters are deep enough to be GTI seats therefor more likely from a GL.
That is correct, they were only an option on GL's with dragen green paint, VR's and GTI's never got them so they are standard seats.
I didn't know its only the GL's which came with these grey leather interiors, I would have just thought they where an optional extra for all trim levels, as I found this original looking VR6 with the grey leathers so but maybe they were added at a later date

he wasn't best pleased understandably, but it was worth a try

They weren't only an option on Dragon green mk3's, mine came from a lightish metallic blue GL, very similar to the OP's car. It had only done 30k miles, so the seats are in great condition!
As mentioned, the bolsters on the back section are ever so slightly smaller than my old GTI seats, but the bolsters on the seat section actually seem a little bigger, certainly more huggable/holdable.
They are indeed grey, but a very light shade of.
I didn't know there where so any interior variations for mk3's, I just thought the grey ones that you have were just gti seats but covered with one of 3 leather colours and with different stiching patterens in the centers... In saying that, I've only just noticed that the grey/cream (grey) ones which I'm after are not actually recaros today. They looked pretty similar until i put two pics of them together and I noticed the recaros have bigger head rests and bolsters and different stiching in the centers again.
I came across this last night, these would be my ideal seats... (see 5th picture down):
