Comment(by dustymugs):

 Correct, if exclude_nodata_value = FALSE there is no difference between
 ST_NearestValue and ST_Value.  There would be no performance difference in
 that situation.

 Assuming you're talking about the possibility that there is no value in
 the tile when reaching the edge of the tile, there are checks in place to
 prevent infinite loops.
