Could we expect to see superVenus type planets without clouds? I know some hot gas giants should be too hot for water vapour clouds so would be essentially cloudless- these are the so-called clarified Jovians

Clarified Jovians fall into the range 350-900 Kelvin; Venus has a temperature of 730K at the surface but it has clouds of sulphuric acid droplets at higher altitudes where it is cooler. I'd expect most superVenus type planets to have high altitude clouds of some sort.
But if a superVenus is hot enough to be clarified completely, you should be able to see the sky from the surface- I'd expect it to be creamy white, if the atmosphere was above 40 bars.
