Th thing is if one is concerned about the water temp in the Bright Whites cycle, Steam can also be selected. The Bright Whites cycle I use for all white loads and never have an issue with stain removal. I also use German Persil Universal MegaPearls so that alone makes a difference. Tide w/Bleach powder does an amazing job used with this cycle. The other thing is the fact that if one needs to have 150F water temps, the Normal cycle does allow it to happen and will extent the cycle to 1 hour and 40 mins..and the washer gets hot or even the Allergiene cycle does the same.
Most cycles that I use are Normal for darks/colors, Bright Whites for whites and white towels, Towels cycle for Towels....that is the longest cycle I might add...it can extend the cycle time from what it says at sensing to in reality 2+ hours later. I will have to say that when I use the cycle it is the last load of the day for laundry. The wash cycle on that is not long, its the rinsing and spinning that consumes the time.
The Bedding cycle...it was called Bulky on the 3570 washer...does quite well, but, extraction is short and so is the spin speed capped at 600 rpms. One can do a Spin Only and get more water out of the load if need be.
