    According to notebookcheck, the Razer Blade 15 Studio Edition has this:

    17-9750H

    3840 x 2160 x 15.6" OLED (Samsung SDCA029)

    Capacitive Touch (using an added digitizer, as the stock SDCA029 has none)

    PWM = 0 (According to desertlap, by using a "custom controller, as the SDCA029 apparently comes with a PWM contoller).

    Back in July, in an article on the SDCA029, notebookcheck wrote that the SDCA029 was non-touch and that:

    "The main (and possibly only) OLED panel being used for 15-inch laptops is the Samsung SDCA029...Unfortunately, pulse-width modulation (PWM) is an issue with this and all other OLED displays at the moment. This is because the OLED as a technology uses PWM to modulate brightness."

    Referring to their review of the Alienware m15 with the SDCA029, notebookcheck wrote that:

    "The display backlight flickers at 60.24 Hz (Likely utilizing PWM)....The frequency of 60.24 Hz is very low, so the flickering may cause eyestrain and headaches after extended use."

    Studio edition? Really? But no active digitizer? No 360? I guess it's for video editing.

    I thought PWM was an inherent attribute of the panel, but I guess not.

    It's a good trick if the Razer's display can pulse in a way the oscilloscope can't detect. I suppose the human eye would also be unable to detect it.
