It doesn't matter... That turbo is done for... Pull it out and replace what's broken... Hopefully just the CHRA. If you continue to run it it will wobble, blades will impact the housing, and you will send shrapnel throughout the engine. I would not start that motor one more time, personally.
It's definitely possible that what you're seeing is the result of something wrong on the compressor side that caused wobble and broke the exhaust impeller off on the housing.
You have less than base boost which means either the wastegate is open (you said it's not) or there is an intake leak preventing you from building boost or the turbo is damaged. We already know the latter is true.
Another possibility here is an intake leak, which caused a turbo overspeed, and that's what wrecked the blades. Pulling the inlet side off will tell you more, but you might as well pull the whole turbo off since you cannot continue to run it anyway.
