Is the Android device identifier sensitive?

Question

I got device identifiers from the system in lowercase letters. Some Device ID applications in PLayStore only return uppercase device identifiers. I heard that these identifiers for iOS are case sensitive .

Are Android device identifiers case sensitive?

I also appreciate the documentation link.

EDIT: More precisely, as you see here , the device ID has been read

f07a13984eed116a

is the same device as

F07A13984EED116A ? Or the last device?
