Do you mean the "disappeared" profile 4? There's no much info about it, but seems like it uses an SDR base layer, so you mean it's then using the EL to encode all the highlights?
Profile 7 is different, it looks like some sort of difference between bit depths. Being low resolution and low bitrate it should only improve "effective bit depth" marginally. And yeah being a "gradient enhancer" it technically shouldn't look much difference, if any.
