No looks as the previous caliper.
Are you of a certain age like me and can remember when bikes had the boot/bellows/dust seal and never really had a brake piston problem.
I did ask them to check the hub carrier bearing as I see movement when pulling and pushing the rear sprocket at 3 and 9 oclock-- des yours have any movement ?
