Logical yes, accurate, no.
The difference in altitude and corresponding pressure will not affect obstructions in those with OSA if a cpap is not used and should not increase the severity of osa. at very high altitudes, the less O2 will cause deeper breathing to compensate. This is due to the pressure being equal in the lung and the atmosphere.
A cpap must have altitude compensation or be manually adjusted to deal with the AMBIENT pressure. if not, the delivered pressure will not be the pressure initially set and will be insufficient to maintain the airway.
Someone may correct me if my physics in incorrect.
