ENR and Bleach Bypass are two different processes. On the movie Evita the lab retained only about 38% of the silver (ENR process = Variable process from 0% silver to 100% silver) and they did a complete bypass in Seven (they left 100% of the silver in the print). The look depends on other factors as well. Different stocks, exposure etc. On Seven they flashed the negative (to soften the contrast by darkening the highlights and leaving the blacks very dark) and pushed the 5283 stock one stop. So, "Bleach Bypass" can be quite different. The technique discussed above gets you close. Then, fine-tune until you get something you like or that is close to your references.
