Nice job repairing that without removing the socket, or melting it!
Looks to me like the IC was probably rammed right the way down in the socket and the screwdriver didn't go far enough in.
As soon as it was levered up, it slipped off the socket and went straight down onto the PCB, leaving that nasty witness mark on the socket plastic.
On the second try it went further in and lifted the chip, with the blade leaving those two parallel witness marks.
Advice to the audience as I think Ian already knows about these tools:
If you're swapping ROMs or chips around, spend ~£10 on a Wera P/N 127456 "Kraftform 1429". It's sold as either the "Micro Chip Lifter" or the "Lifting Fork".

It should be fairly obvious how this is used and why it causes less damage than a screwdriver might...
