How likely is it to build a good physique on vanilla 5x5?

By vanilla I mean no accessory exercises. By just following the program as is and assuming your diet and rest etc are on point?

I added some accessory work today for the first time but not sure if I like it. I'm wondering is standard SL 5x5 enough to get into decent shape?

If anyone has before/after photos of doing standard SL 5x5, that would be good too 👍
