It has to do with reference point. With DTM, the bar has been raised.
DTM is the next chapter, but are there compelling differences between the current DTM solutions?
While it's still early in the feedback phase of the new JVC DTM software update, some of that feedback suggests the new DTM feature set controls lack the nuance and/or granularity, of the madVR or Radiance Pro alternatives.
So for me it begs the question, will the JVC DTM controls have the flexibility for owners to change/adjust parameters for some of the Low, Mid, High presets? For instance, if on a scale of 0 - +12, Low = +3, Mid = +6 and High = +9, what can be done if High = +11 would have been a better parameter setting option?
The ub820/9000 have Low, Mid and High dynamic range presets, but the user can over ride those presets and manually adjust anywhere along the -12 - +12 dynamic luminance adjustment range.
This not to say the available controls within the JVC DTM feature won't be a good upgrade over static ATM, albeit less flexible than the alternative DTM solutions.
