This is a good tenant and I know this was a complete accident, but the bamboo flooring was new as of 2013 and now will require a good bit of money to replace/repair. 

Do I just repair and give them nothing?

Especially considering the quality difference.

Many museums that allow photos nowadays play with variable-colored light in their indoor spaces to keep tourists with nicer digital cameras from accidentally getting the highest-quality shots of their pieces.The appraiser is going to get fewer opportunities to get shots to justify a lowball appraisal if your property is very bright and the lights are at the daylight-colored range.

Invest in a quality underlayment that will help adjust for any imperfections in the subfloor.

I've had a maintenance person that will usually get in and clean, repair, paint, and do everything needed to rehab an empty apartment into one that is rentable when a tenant vacates the property.

Had my agent bid on a house that needed $50k in repairs on Hubzu that was for cash only investors, trying to avoid competing with owner-occupiers.

Also consider what kinds of repairs you would be responsible for under the COA.

I don’t like to have a loan of more than about 50-60% of ARV after the repairs are done.

Quality of houses is varied street to street.
