Hi ! I have similar bug for Magento 2.2. In my case was error on price-utilis.js. JS method "toFixed" has hardcoded 2 and on the detail view the price was replaced -> not values from configuration. am.toFixed(precision) helped me. Here is all method. Modify is only one line.

   `function formatPrice(amount, format, isShowSign) {
    var s = '',precision, integerRequired, decimalSymbol, groupSymbol, groupLength, pattern, i, pad, j, re, r, am;
    format = _.extend(globalPriceFormat, format);

    // copied from price-option.js | Could be refactored with varien/js.js

    precision = isNaN(format.requiredPrecision = Math.abs(format.requiredPrecision)) ? 2 : format.requiredPrecision;
    integerRequired = isNaN(format.integerRequired = Math.abs(format.integerRequired)) ? 1 : format.integerRequired;
    decimalSymbol = format.decimalSymbol === undefined ? ',' : format.decimalSymbol;
    groupSymbol = format.groupSymbol === undefined ? '.' : format.groupSymbol;
    groupLength = format.groupLength === undefined ? 3 : format.groupLength;
    pattern = format.pattern || '%s';

    if (isShowSign === undefined || isShowSign === true) {
        s = amount < 0 ? '-' : isShowSign ? '+' : '';
    } else if (isShowSign === false) {
        s = '';
    }
    pattern = pattern.indexOf('{sign}') < 0 ? s + pattern : pattern.replace('{sign}', s);

    // we're avoiding the usage of to fixed, and using round instead with the e representation to address
    // numbers like 1.005 = 1.01. Using ToFixed to only provide trailig zeroes in case we have a whole number
    i = parseInt(
            amount = Number(Math.round(Math.abs(+amount || 0) + 'e+' + precision) + ('e-' + precision)),
            10
        ) + '';
    pad = i.length < integerRequired ? integerRequired - i.length : 0;

    i = stringPad('0', pad) + i;

    j = i.length > groupLength ? i.length % groupLength : 0;
    re = new RegExp('(\\d{' + groupLength + '})(?=\\d)', 'g');

    // replace(/-/, 0) is only for fixing Safari bug which appears
    // when Math.abs(0).toFixed() executed on '0' number.
    // Result is '0.-0' :(

    am = Number(Math.round(Math.abs(amount - i) + 'e+' + precision) + ('e-' + precision));
    r = (j ? i.substr(0, j) + groupSymbol : '') +
        i.substr(j).replace(re, '$1' + groupSymbol) +
        (precision ? decimalSymbol + am.toFixed(precision).replace(/-/, 0).slice(2) : '');

    return pattern.replace('%s', r).replace(/^\s\s*/, '').replace(/\s\s*$/, '');
}`

Was fixed with last commit. Thx @cdiacon
