Have I messed up the brake calliper?

I made a stupid mistake of riding with the disc lock on. Not full rev riding but a abit of engine torque. Have I messed up the calliper? I tried looking online and couldn’t find any pics of what it looks like from the other side. Reason why I ask is because I spotted some grooves on one side which I didn’t notice before. Bike rides ok and no leaks. Could just be me paranoid. I will be using the lanyard from now on so I don’t forget.
