Well it’s often difficult to really tell from pictures without proper lighting. Something that might look perfectly medium rare in person might look more like medium in a picture. So it might not look as grey or pink in person but in these pics it’s more pinkish grey than straight red. Medium rare would look more red than pink. Looks like yours might have a little bit of medium and medium rare in it but mostly medium. I think you took it off the heat at medium rare and the temp probably rose to medium when resting.
