I don't think so. I think with white snakes it's much more noticeable because the pink shows through and can be easily seen, where darker snakes it wouldn't be noticed.
I have had two snakes go septic. One was Matilda. You can read about her here:

The other was a male Tarahumara. I had taken him to the vet for what presented as swollen eyes, and he was being treated with a topical ophthalmic ointment for them. It turns out that he had a scratch in his throat/esophagus just behind his head, the wound site had gotten infected, and the internal infection was causing his eyes to swell up. Since we didn't know what the underlying issue was, he also went septic and passed. He never looked pink but Taras are pretty dark-colored boas with orange/apricot bellies so it wouldn't have been obvious.
