While regular Gimp does not have a dedicated LAB mode, the (rough) work flow can be paralleled using a couple of utilities.
G'mic plug-in http://www.gmic.eu does allow adjustment in LAB for color curves

and for the sky as well, the L curve: https://i.imgur.com/mKdoB5o.jpg
But that needs to be masked and the luminosity masks script can be used. see: https://patdavid.net/2013/11/getting-aro...masks.html

Thanks for the leads, Rich! The G'MIC link is particularly interesting, those folks update so often that it is hard to keep up! . . .
