There is NO HDR!!!! function on this device. Also, from my reading & use of this device, VERY few people seem to use the WDR function as it has compromises which you can search the forums & the web for information & or YouTube for video samples of. So, given that IF very few people even use WDR & probably fewer people STILL test these firmware mods AND so would test WDR, then you are not likely to get spoon fed the result that you are looking for. SO, why not just download the firmware mod, test it yourself & you will very quickly get an idea of what it will do for your needs, vs. waiting around for someone else to do the tests for you. Eg: I might think that the function is useless for my needs, but it may work great for you, but then you may not test it based on my poor review. It is so extremely simple to test AND the firmware mod programmers are already doing us a HUGE service, so maybe help them out & do a test & post samples & what you think? That way, everyone benefits. I look forward to your test results, but I'm not going to do it for you based on my not past experiences with WDR.
