The water is going to evaporate at some rate with or without a cover. You need to add water to the pool at least once per week. Evaporation rates without a cover would be close to 1.5" per week in most areas. k
The difference is not significant.
Yes, salt can evaporate with pool water. As pool water evaporates, the salt content remains in the pool. When the water evaporates, the salt will be left behind and may accumulate in the pool.

In Arizona, it is best to drain your pool in the Winter. You might be wondering, why shouldn't I drain my Arizona pool in the summer?The answer to that is that if you drain your pool during the hot, dry Arizona summer months, you risk causing expensive damage to your swimming pool. The floor of the pool can crack due to the heat and lack of moisture. Draining your Arizona pool in the summer is also bad for the desert environment where water is scarce. The pool water that is drained out will mostly evaporate instead of being used to water the lawn or other plants on the property.
It's best if the water is cleaned before you close up the pool.
