Interesting! The PS3's sled is actually pretty complex, as they used the same objective lens for all three wavelengths (IR for CD, red for DVD, and blue/violet for Bluray). A lot of other sled designs have two objective lenses, as CD/DVD uses one path, and Bluray uses the other path, which makes them simpler, but bigger and more unwieldy.
That would suggest that the majority of the optics are working ok, as they're shared. However, there's a few bits (like the "zoom" lens for layer selection) that might be a bit more Blu-ray unique.
